Abstract

We have studied the distribution of charged particles recoiling from high p_T(> 3.5 GeV/c) direct photons and neutral pions in pp collisions at √s = 63 GeV. One expects a different mixture of quark and gluon initiated jets in the two cases, with predominantly u-quark jets recoiling from direct photons. No significant differences are observed in our momentum range apart from the charge composition, with a larger positive to negative ratio for particles with p_T > 1 GeV/c opposite direct photons than opposite π°.
